LOUIS KOWITZ, OF LAWRENCE, MASSACHUSETTS.

sArnrv-nazon.

To all'wkomz'tmay concern: Be it'known that I, LoUIs Kowrrz, a citizen of the United States, and a,resident of Lawrence, in the county of Essex and State of Massachusetts, have invented an Improvement in Safety-Razors, of which the simple and elficient razor of the character described. The invention further has for market or after the manner of the old fash-- ioned'razor as will be described.

its ob'ect to provide a razor which is capable 0 being used after the manner of the safety razors now commonly found on the These and other features of this invention will be pointed out in the claims at the end of the specification.

Figure 1 is a plan view of an inverted safety razor embodying this invention, with the handle shown in section.

The safety razor herein shown as embodying the invention is provided witha bladesupporting plate or member 10, and with a plan of the. blade-supporting guard plate. or, member 12 which are connected together at one end by a pivot pin passed through ears 14, 15, on sald members respectively. The supporting member 10 shown separately in F 1g. 5 is provided with aprojection 16 which is deslgned to pass through a slot 17 in the blade 18, when the latter is-placed upon the supportingmemher, said projection acting to properly po-' sition the blade 18 :with relation to the .supporting member.

The guard member 3.2 is also provided "Specification of Letters iatent.

with a slot 19 through which the projection 16 passes to enable the guard member to be brought into engagement with the blade 18 and secure the latter in fixed relation to the supporting member. v

The blade 18 is made wider than the supporting member and is provided with cutting edges at its opposite sides which project beyond the sides of the supporting member 10 and with which cooperate guards in the form of teeth or fingers 20, extended from the oppositev sides of the member 12, and which serve to protect 'theface frombeing cut by the blade. 7 I Provision is made for locking the guard member in what may be termed its closed position represented in' Fig. 1, and to this end, the guard member has mounted upon it a cam plate or segmental disk 25wh1ch is mounted to. turn on apivot pin 26 and is provided witha thumb piece or handle 27.

The cam plate or disk 25 cooperates with an inwardly projecting lip 28 on the upturned front end 29 of the supporting member 10, 'to force the free end of the guard 'member 12 toward the supporting member and to lock the guard member in fixed relation to the supporting member, as represented in Fig. 1. j

The blade 18 is provided with inwardly curved ends 30, 31, (see Fig. 4), whichenable the blade to be quickly and easily applied to and removed from the supporting member and clear the inwardly projecting lip 28 and at the same time provide the blade with cutting edges of full length as represented in Figs. 1 and 3.

.When it is desired to remove the blade, the locking device or cam 25 is turned from underthelip 28' and into substantially the position shown in Fig. 6, whereupontheguard member 12 is free to be turned on its pivot into a thereby rendering the bla e accessible for removal from the guard memberin itsv turned-back or open position. The guard member is then turned down, and the cam turned under the lip 28.

The cam 25 and lip 28 are constructed so as .to force the guard member against the supporting member 10, Y

. blade and firmly clamp the latter against the position substantially at. right anglesto the supportin -member 10,

supporting member. .When it is desired to assemble the parts for.

The razor is provided with, a handle 40 which is detachably secured to the guard member 10, and provision is made for at .taching the handle to the guard member so that it may extend at an angle tliereto or substantially-in the planethereof, whereby the razor maybe used in the manner of the Y ordinary safety razor, or may be used in the manner of the old-fashioned razor.

To-these ends, the handle 40 is provided at one end with athreaded socket 41 into which is extended a threaded rod 42 provided with a head 43, which is designed to be engaged with two curved flanges 44,45, which extend toward each other from end flanges 46 on a substantially semi-circular member 47, which is soldered or otherwise attached to the guard member 12. The in wardly. extended flanges 44, 45, form a curved .uideway for the head 43 to slide in and t ese flanges extend transversely of the guard member and terminate at one end 1 away from the guard member a suflicient distance, represented by the space .48, Fig.v

2, to permit the ready insertion and removal of the head 43' into and from said guideway. I i

When the head 43 has been inserted; into its guideway, it may be moved-therein so as to adjust the handle 40 into different angular positions with "relation to the guard member,"and when in the desired position, the handle may be turned So asto draw the threaded rod 42. into its socket 41 and thereby cause the head 43 to firmly engage the flanges 44,45, and secure the handle in fixed relation to the razor.

Tosecure the handle to the razorjmembers so that it extends from one end thereof substantially in the plane of the guard member 12, the end of the handle opposite the head 43 is flattened more or less and'tapered and is passed under a bridge member 50, which may be formed by upwardly bending the intermediate portion of the pivot pin 13 (seeAFig. 9). 1 I

Provision is made-for frictionallylocking the handle to the guard member a 'ainst accidental removal and for maintaming the handle in a fixed relation to the guard memher. To this end thegu'ard member is pro-' vided with a springtongue 52 (see 7), betweenfihih and the guard member 12 the tapered end of the handle is inserted.

'The tapered end of the handle'may be provided with a transverse groove 53 for en gagement with a bend 54 in the spring tongue, "which parts cooperate to form a I lock against accidental removal of the handle. The spring .tongue'52 may be formed from the guard member by turning baqk the portion thereof which is cut to form the slot 19.

By reference to Fig. 8,'"it will be seen that thesafety razor may be used in the same manner as the old-fashioned razor, which is preferred by some users, and with the handle arranged as shown in Fig. 2, the .razor .may be usedlike the ordinary safety razor.
